Title:
UPLINK TIMING ALIGNMENT FOR MULTIPLE TRANSMISSION POINTS
Document Type and Number:
WIPO Patent Application WO/2023/206103
Kind Code:
A1
Abstract:
Methods, apparatus, and systems that enable reliable uplink timing alignment with multiple transmission points are disclosed. In one example aspect, a method for wireless communication includes receiving, by a terminal device, a message comprising a timing advance command and determining, by the terminal device, at least one transmission parameter based on the message. The at least one transmission parameter is associated with the timing advance command. The method also includes applying, by the terminal device, the timing advance command to a transmission associated with the at least one transmission parameter.
